Active clinical trials for "Hepatitis A"

149 HBV carriers with inadequate serum vitamin D levels were randomized to two groups: one is supplied with vitamin D and another without as controls. The markers of HBV replication were compared before and after treatment.

The goal of this study is to assess patients' attitudes and knowledge of Hepatitis C, analyze the variables that may influence patients' knowledge, and educate patients on Hepatitis C.

Severe alcoholic hepatitis, defined by a "Maddrey discriminant function" above 32, is associated with significant short-term mortality. In patients with liver disease, studies have shown alterations of intestinal bacterial flora and an increase in intestinal permeability leading to bacterial translocation across the intestinal barrier. The mechanism involved may be an activation of intestinal macrophages with a local release of cytokines like interleukin-8 (IL-8). Calprotectin is a protein present in large amounts in the cytosol of neutrophils. Its presence in feces is related to neutrophil migration in intestinal lumen. Thus, fecal calprotectin may be used as a marker of intestinal inflammation. There is evidence that fecal calprotectin levels are increased in cirrhotic patients dependent on the severity of the disease. The predictive value of fecal calprotectin for the outcome of severe alcoholic hepatitis has never been evaluated. The main objective of this study was to determine if the initial level of fecal calprotectin and its variation after 7 days had a predictive value for the outcome of severe alcoholic hepatitis. Secondary objectives were to determine if fecal calprotectin concentration was correlated with blood concentration of Lipopolysaccharide (LPS) binding protein and predictive of infections.

The purpose of this study is to evaluate pharmacokinetics and safety data including serious and other adverse events, physical examinations, vital signs, 12-lead electrocardiograms (ECGs) and clinical laboratory results (including biochemistry, hematology, and urine).

Effective all-oral medications are finally available to cure hepatitis C virus, which affects more than 4 million Americans and one-in-four people living with HIV. However, many barriers exist that prevent people with HIV/HCV co-infection from getting this curative treatment, including low knowledge, competing demands, and drug interactions with HIV medications. This study evaluates if a hepatitis C nurse case management intervention in an HIV primary care clinic will improve patient attendance to hepatitis C care and help people start hepatitis C treatment earlier. Half of the participants will receive brief case management with a nurse, while the other half will receive usual clinic care.

Treatment cessation in chronic hepatitis B is associated with high rates of disease relapse. However patients who achieve the seroclearance of hepatitis B surface antigen (HBsAg) (<0.05 IU/mL) show good off-treatment durability after treatment cessation. Through the quantification of HBsAg, the study aims to investigate how low should quantitative HBsAg be before once can achieve successful disease control after treatment cessation.

The first purpose of this study is to test the body's protective reaction (making antibodies) to a licensed hepatitis B vaccine (Recombivax-HB) after it is injected either in the arm fat or muscle. Hepatitis B virus is an important cause of liver disease in humans. More than 21% of healthy adults over age 60 years demonstrate evidence of previous Hepatitis B infection using a common blood test. The second purpose of this study is to learn more information about other reasons (such as body fat content, gene types, etc.), why older people respond less well than younger people to vaccines. The Investigators will also learn more about the ability of certain white blood cells, called T cells, to respond to protein signals in the blood. T cells do not seem to respond as well to these protein signals as individuals age. The Investigators will compare results to a younger group of volunteers who have also been vaccinated with hepatitis B vaccine.

This 2-part, randomized, double-blind, placebo-controlled study will assess the safety, pharmacokinetics and pharmacodynamics of RO5428029 in healthy volunteers and patients with hepatitis C infection. Cohorts will be randomized to receive either RO5428029 in ascending doses or placebo for up to 7 days (patients) or up to 14 days (healthy volunteers).

A Double-Blind, Randomized, Placebo-Controlled, Multiple Dose Ranging Study Evaluating the Safety, Tolerability, Pharmacokinetics and Antiviral Activity of GS-6620 in Treatment Naïve Subjects with Chronic Hepatitis C Virus Infection.

Background: According to recent estimates, the prevalence of Chronic Hepatitis C (CHC) in Canada is three times more common in First Nations (FN)and Metis compared to non-FN populations. Moreover, once infected, the progression of CHC to cirrhosis and/or hepatocellular carcinoma is greater in FN patients due to the increased prevalence of alcohol abuse, obesity and diabetes in this segment of the population. Research Plan: This research proposal consists of three parts. The objective of Part I is to document the response to anti-viral treatment for CHC among treatment-naïve FN and Metis and Caucasian (hereafter referred to as non-FN) patients residing in three urban Western Canadian centres (Winnipeg, Saskatoon and Regina). Demographic, clinical and response to treatment data in a total of 160 patients (80/group) will be collected at the above centres and transferred to the Section of Hepatology at the University of Manitoba for statistical analyses. In Part II, the applicants will document and compare the immune responses to HCV proteins throughout the course of therapy in FN, Metis and non-FN patients. In the final part, direct economic costs of CHC care in FN, Metis and non-FN patients will be ascertained and future costs predicted. Hypotheses: Part I - The rate of sustained virologic response (SVR) to treatment for CHC is higher in FN and Metis compared to non-FN and no Metis patients. Part II - The immune response to HCV proteins during anti-viral therapy for CHC is enhanced in FN and Metis compared to non-FN and non-Metis patients. Part III - The direct costs of health care utilization and delivery for CHC are similar among FN and Metis and non-FN and non- Metis patients.
